The Mouse House scores big with first-quarter earnings of 79 cents a share, compared with 37 cents a year earlier (the most recent results include a gain of $1.01 billion from the sale of interests in E! Entertainment and Us Weekly). Excluding the one-time stuff, quarterly profit was 50 cents, beating the estimates by a dime. Much of the good news stems from strong DVD sales for "Pirates of the Caribbean: Dead Man's Chest" and "Cars," as well as solid results from both ESPN and ABC. Disney CEO Robert Iger is really on a roll - he should enjoy it while it lasts. Not that I'm presaging trouble - it's just that in Hollywood the good times never last. Results were announced after the market closed. Bloomberg
